Omega-3 fatty acids reduce risk of Covid-19, hospitalization and death

With each passing day, Covid-19 is a little more of a thing of the past. Let's hope it stays that way. But should the misery of recent years ever repeat itself, it might be good to know that we can protect ourselves against respiratory viruses through supplementation with natural substances such as omega-3 fatty acids.

Epidemiological study
Researchers at the University of South Dakota in the US analyzed the data of 110,584 Britons, collected in the UK Biobank project between the end of 2020 and the beginning of 2021. [Am J Clin Nutr. 2023 Feb;117(2):357-63.]

The researchers knew how much DHA [structural formula shown below] the participants had in their blood, and divided the participants into 5 equal groups based on this. The Americans then looked at whether there was a relationship between DHA levels and testing positive for Covid-19, the risk of hospitalization and death.

Results
The more DHA was present in the blood of the study participants, the lower their chance of a positive test and hospitalization as a result of a corona infection.

The protective effect remained intact when the researchers used statistics to eliminate the effect of factors such as "age at start of pandemic, sex, race, waist circumference, Townsend deprivation index, smoking status, education, self-reported health, blood pressure, slow walking pace , fresh fruit, dried fruit, fresh vegetables, cooked vegetables, and grain fiber".

The protective effect of DHA is less clear when it comes to death. The study participants in the quintile with the highest concentration of DHA in their blood did not have an even lower risk of death than the study participants in the fourth quintile.

The researchers keep open the possibility, read between the lines, that this is because the fifth quintile contains a relatively large number of relatives who use fish oil supplements for health reasons. The researchers have not been successful in filtering out these lifestyle factors.

Trial
In Western nations such as the US, the UK, the Netherlands and Germany, universities apparently did not consider it necessary to study the effect of natural substances such as zinc, quercetin, vitamins C and D and omega-3 fatty acids in Covid-19 in trials. Universities in nations that the arrogant right-thinking, progressive, and developed West look down upon made a different assessment.

In Iran, for example. In Iran, researchers from Sabzevar University of Medical Sciences conducted a trial in which 128 seriously ill Covid patients in the ICU received tube feeding. The researchers had divided the patients into 2 groups. One group received a regular diet for 14 days, the other group also received 1 gram of fish oil daily. This fish oil contained 400 milligrams of EPA and 200 milligrams of EPA.

The chance of survival was no less than 7 times greater in the supplement group than in the control group.

Surviving Covid-19 thanks to GABA supplementation GABA supplementation may not only improve sleep quality and reduce stress, but may also protect against the deadly effects of a coronavirus infection. Animal data.	Yes, vitamin D supplements protect against Covid-19 Vitamin D supplements protect against Covid-19 to an extent which would make a manufacturer of Covid-19 vaccines more than satisfied. Meta-study.	Quercetin makes zinc a better Covid protector Zinc supplementation can reduce the risk of corona infection and complications. The protective effect of zinc is probably even stronger when co-supplemented with quercetin.
